I've noticed this over the last couple of days. I have unlimited data, so have my email on autosync. I also get a lot of emails - so if I wake up (as today) to no new ones, I know something is wrong... I have the autosync thing enabled, but even when I got to the settings and ask it to sync now, it wont - it wont even try - there's no circling sync symbol, even for a moment - even unchecking then rechecking the things for syncing wont work. I have to turn it off then on before it'll do it again. Any ideas what's going on - when out and about it sometimes takes me a while to notice it's not working, and turning off and on is a faff.
